FEED MECHANISM FOR AUTOMATIC CARVING-MAC-IINES.

Patented May 11, 1909.

Application led Novmberll, 1903,. Serial No. 181,436.

To all 'whom 'it may concern.'

Be it known that I, MARTIN DE TAMBLE, a citizen of the United State-s,residing atIndianapolis, in the county of Marion and State of Indiana,have inventedv certain new and useful Improvements in Feed Mechanismsfor Automatic Carving-Machines, of which the following is aspecification.

My invention relates to automatic carving machines, and has specialreference to improvements upon those machines wherein a transverselymovable feed-table is employed on a longitudinally movable bed. In suchmachines, the bed with the table is regularly reciprocated, and, as thebed approaches the end of its stroke in either direction, the table isfed slightly to one side, in order that the carving-tools may make freshcuts during the return stroke of the bed.. The devices heretoforeemployed for feeding the table in'this manner havebeen of. suchconstruction .and arrangement as to require considerable time for theiroperation, with the result that. the table has not been set oversimultaneously with the termination of the longitudinal stroke of thebed and` table, nor approximately so. This has occasioned the irregularaction of the cutters. Furthermore, the present feeding-mechanisms areincapable of either fine adjustment or great range of aduiustrnent yetboth these qualities or abilities are .essential to the .lineperformance of a variety of work. The automatic carving machine which Ibelieve to be, of all, the most satisfactory and practical is thatVwhich is made in substantial accordance with Letters Patent No.696,382, granted to Streich and Iuehs, March th, .1902.. This machine,however, is subject tothe foregoing criticism, for it has afeed-mechanism that .is actuated by the last part of the stroke of thebed, and

the action of which is rendere-d still more uncertain by the presence ofsprings or cushions between. the bed and its driving-mech- These springsor cushions are compressed by the movement of the table against theresistance of the tracer and the tools, and as a result, when the driveris reversed, the table has a short, independent; forward movement,followed by a period of delay, be-

fore it is picked up by the reversely operated driver. jectionable, scfar as the feed-mechanism is concerned; but `the intermittency .and yetcontinuousness of the action obtained .inthe This feature of the'machine is ob-` Vtable through the employment of the yieldingconnections is of the greatest advantage in reproducing high reliefcarvings, and should be retained.

My conception is that the transverse feeding movements of thework-table, instead of preceding the moment of table-delay, should takeplace during such period and just precede the beginning of each strokeof the table and bed; and the object of this invention is to provide animproved table-feeding mechanf ism, whereby the table shall be fedsimultaneously with or ust preceding the beginning of each stroke. 4

Another object of my invention is to .ro-

vide a table-feeding mechanism that sha be readily adjustable to varythe feed of the table; and which, furthermore, may be regulated oradjusted during the operation of 1- the machine. Y Still another objectof my invention is to yimprove 'the means orV mechanism that is employedfor reversing the. direction of the transverse..movement or feed of thetable g and still another object of my invention is to provide atable-feeding mechanism that shall constitutean unbroken connectionbetween the bed-driving .mechanism and the table; throughout which, theparts shall be in positive engagement at all times.

' /Vith these objects in view, my invention consists in the improvementsin feed meel anism for automatic carving machines as hereinafterdescribed and particularly pointed out in the claims.

The invention will be more readily understood by reference to theaccompanying drawings, forming a part of this specification, and inwhichi- Figure 1, is an elevation of the front end of an automaticcarving machine equipped with '3a feed mechanism embodying my invention,the .upper portion of the machine being broken away; vFig. 2 is an endview of the partsshown in Fig. 1 Fig. 3, is a plan view ofthe machine,the feed tableV being removed, to disclosethe underlying parts; Fig. l,is end View ofthe oscillatory,feed-clutch; Fig. 5, is a sectional viewthereof, substantially on the line xof Fig. 4, Fig. 6, is an end view ofthe variable stroke feed-pawls; Fig. 7, is a side view thereof; and Fig.8, isa sectional view of the hand feed-control.

As shown in the drawings, 2 represents ,the

frameofan automatic carving machine, 3

. These parts are:

is the longitudinally movable bed, and 4 the transversely movablefeed-table that rests upon the bed. 5 represents the bed-drivingmechanism, which, with the shifter, 6, operates to reciprocate the bed,3, upon thc frame, the same being automatically reversible. Theconstruction of these parts ofv a carving machine is too well understoodto require detailed explanation herein.

A worm, 7, is usually employed in connection with the driving device,and this coperates with a rack, 8, that is yieldingly connected to thebed by springs or cushions, 9, above referred to. In place of the worm,7, a screw may be used with a nut in the center of the table, havingsprings on either side thereof. ln such case this nut will take theplace of and operate as the rack, 8. rllhese cushions, 9, and theirfunctions are fully described in No. 757,243; and the purpose thereof isto permit the bed and feed-table to lag with respect to the movement ofthe driving-mechanism, Whenever the table encounters special or abnormalresistance from the tracer and the cutters which operate upon the atternand work that are upon the table. t is obvious that there is a moment ofcomplete stoppage or delay at the end of each stroke of the ed,preceding the actual reversal of the driving-worm, 7. This period ofdelay is prolonged by the time required for the recovery of thecushions, following the stopage of the worm, 7, and by the time requiredfor the picking up or starting of the bed by the driving-worm, throughthe medium of said cushions. lt is during these periods of delay that ldesire to feed the table upon or across the bed, although, as it will beevident hereinafter, the feed movement may, and would, in the absence ofthe cushions, with good results, take place simultaneously with theactual reversal of the bed.

My feed mechanism comprises five principal elements or mechanisms, that,together, extend between and positively connect the bed-drivingmechanism and the feed-table.

The clutch, A; the feedregulator, B; the pawl-throwing disk, C theratchet mechanism, D, and the sliding-connection, E, between the ratchetmechanism and the feed-shaft or spindle, 10, wherefrom the actualtransverse movement is communicated to the table. A, the first of themechanisms, comprises two friction-disks, 11 and 12. The part, 11, isarranged on a shaft, 13, having bearings, 14 and 15, in the machineframe and carrying a large beveled gear, 16. The shaft, 13, and theclutch-part, 11 are driven by the pinion, 17, this pinion being on theworin shaft or on a shaft just below that carrying the Worm orbed-driver, 7, and rotated in time therewith by any suitable means, suchas suitable gearing 7. Said shaft, 13, is therefore first driven in onedirection and then in the other, according to the reversals of thedriver by the mechanism, 5. In Fig. 1 the relation of the shaft carryingthe worin, 7, to the shaft beneath, which latter carries the gear, 5, isclearly shown by dotted lines. In Fig. 3 the lower shaft is covered andconcealed by the worin shaft and its bearings. The gears 5 and 17 areboth on the lower shaft. The second part, 12, is secured to theoscillating or rocking shaft, 18. On one end of this shaft is thebearing, 1), in the end of the disk, 1 1 the two shafts,13 and 13,abutting therein. The opposite end of the shaft 1S, has a bearin T 20,in the side frame of the machine, and on its outer end carries thepawl-throwing disk, C. The part 12, as shown in Fig. 5, is cup-shaped,to receive the disk, 11, and said part 12 is supplemented by aspring-pressure ring or disk, 21, arranged on the opposite side of thedisk, 11, and held against the same by springs, 2L., provided on studs,23, that are placed around the part 12. The pressure of the outer disks,12 and 21, upon the disk, 11, may be varied by means of thefollower-nuts, 24, on the studs, 23. Leather washers, 25, are preferablyarranged between the disks, to increase their frictioind engagement.

The second mechanism, B, is the feedregulator, and eonprises a devicefor liniting and adjusting the throw or oscillation of the part, 12, andthe shaft, 1S. This regulator comprises the pins, 26, provided on theface of the disk, 12, and the sliding yoke, 27, with its operating rod,2S. The yoke, as shown in Fig. 4, einbraces the hub, 12, of the disk,12, and is provided with oppositely-extending stop-lugs, 29, 29, thathave curved stop-surfaces, 29. Any suitable ineans may be arranged formoving the rod, 2S, and the yoke; such, for exainple, as the hand-wlmel,30, havin an internally-threaded sleeve or hub, 31, he d in a bearing,32, of the frame and engaging the threaded end, 28 of theregulating-rod, 28. By these devices, the yoke may be so adjusted thatits lugs will engage both pins upon the disk, 12, or it may be retired,to free said pins and the disk, 12, for partial rotation or oscillationby the frictiondisk, 11.

The third element of the feed-1nechanismy is the sinple disk orcross-arm, (l, on the end of the shaft, 18, and to which the lower endsof the pawl-bearing links, 33, 34, are pivoted.

The fourth element is of somewhat more complicated nature, and iscomposed of the ratchet-wheel, 35, arranged on a short shaft, 36,together with the operating dogs, 3f), 4U, that are pivoted on theoscillating levers, 37, 38. rlhe links, 33, 34, have their upper endspivoted to the lower ends of the levers, 37, 33, and said levers arejournaled on the shaft, 36. Said shaft, 36, is rotatable in the smallbearing, 41, arranged in the machine-frame, 2. The ratchet-wheel, 35,has a great number of notches, 35, for engagement with the lll) pins43--44, and each is provided with aA stop-lug, 46, to engage either oneof the -shoulders, 39, 39-40, 40, of the pawl to Which it 1'oelongs Whenthrown to one side, these Weighted levers hold the corresponding ends ofthe pavvls upon the ratchet- Wheel, and when thrown to oppositepositions they operate to engage the other ends of the pawls With saidWheel, 35, whereupon the rotation of the latter' Will be reversed.Though rotatively intermittent, the ratchet- Wheel's direction ofrotation remains the same, so long' asthe Weights, 45, of the paWlsremain unchanged, andthe same may therefore be employed for continuouslydriving or feeding the table across the bed. .v

rilhe shaft, 36, of the ratchet, carries the bevel pinion, 42, arrangedon the inner end of the stationary bearing, 41.` This pinion, with the.parts associated With it upon the reciprocatlng bed of the machine,constitutes the fifth element or mechanism, E, of my machine, thepurpose thereof being to maintain a constant connection between thefeeding-mechanism or ratchet-device and the either of which motions theWork may be fed transversely to the carving-tools.

'vl/*ith the exception of the motion-communicating shaft, 53, that isarranged on the bed of the machine, this invention is not concernedWith'the detailed construction and arrangement of the parts thatdirectly communicate the feed motion to the table, and my inventionadmits of the employment of any style, type or kind of mechanism thatmay be actuated from the ratchet-Wheel or its shaft. *The drawingshereof therefore illustrate only one of the systems of spindles andgears that l may employ on the feed-table. leferring again' thereto, itwill be seen that the shaft, 53, is held in bearings, 54, at the ends ofthebed, 3, and that the gear, 42, is connected therewith by means of abeveled pinion, 51, that is held in a bracket, 52, on the bearing, 41. Afeather-and-slot connection is used between the pinion, 51, and shaft,53, and said shaft is therefore permitted to reciprocate through thepinion, 51, While said pinion is at all times engaged with the shaftto'partially rotate it when motion is impar-ted to theratchet-mechanism, D.

10, represents the main driving-shaft of These the table gearing. At itsouter end this is held in a bearing, 48, and the shafts, 53 and 10, areconnected by the beveled gears, 55 and 57. rl'he inner end of the shaft,10, is held in the slidable bearings, 4, that hang from the table, 4,and gears, 59, are used for connecting the shaft, 10, with thewormshaft, 50, for operating the chucks on the table, 4. The gears, 59,may be placed in mesh or disengaged at the `-will of the operator.

47, 47 represent the table-driving spindles that are arranged inbearings, 453-48 on the bed, 3, and which are connected to the table, 4,by the depending threaded sleeves, 49. Gears, 53, are used forconnecting the shaft, 10, to one of the spindles, 47. This connectionmay be made at the same time with the connection to the Worm-shaft, 50,but ordinarily the worm-shaft, 50, is not driven during the transversemovement of'the table, by the screw-spindles, 47. As shon'n in Fig. 3,the spindles, 47, on the front and back of the bed, are connected by alongitudinal shaft 47. lt will be observed from the foregoing thatpieces of Work and the pattern that are held in the chucks on the tablemay be either rotated or moved transversely across the bed, 3, or, ifdesired, both feeding movements may be used, all from the intermittentmotion of the shaft, 53. The degree of movement imparted to the table byeach stroke of the oscillating paxvls cf mechanism D, may be altered orregulated at any time by the manipulation of the stop-yoke or regulator,B, which alone controls the length of stroke that will be imparted tothe ratchet-panels by the oscillator, C. Furthermore, as theratchet-mechanism, D, is at all times positively engaged and connectedwith the tablegearing, through the medium of pinions, 42 and 51, suchregulation of the ratchet-mechanism may be accomplished withoutinterrupting or stopping the movement of the bed and the table thereon.

rThe uses, functions and advantages of my invention may be summarized asfolloWs:- l/Vhen `the reversing mechanism, 5, is started, the immediateresult is the regular reciprocation of the bed which carries thefeed-table. This reciprocation is brought about by the periodicalreversal of the driver, 7, due to the operation of the shifter by thebed itself. Because of its connection `with the driver, 7, through thegears, 16 and 17, the shaft, 13, with the disk 11 thereon, tf-:ill bedriven continuously in one direction throughouteach operation of thedriver, 7, and until said driver is reversed, whereupon the direction ofrotation of the friction-disk, 11, Will also be reversed. The use ofthesmall pinion, 17, on the driver-shaft, and the large gear, 16, on theshaft 13, considerably reduces the relative number of revolutions madeby the shaft, 13; nevertheless, said shaft is' preferably arranged tomake several revolutions during the operation of the driver. It isobvious, therefore, that eX- cept for the presence of the regulator, B,the shaft 18 would be constantly rotated, and that the presence thereofprevents complete revolutions of said shaft and confines its motions tooscillations that are exactly timed with the reversals of thebed-driver. The operation of the'bed by the worm or driver, 7, is muchmore deliberate than the movement of the oscillating part thereby, andit follows that the feed-mechanism completes its operation before themovement of the table is perceptible.

The frietional engagement between the disks making up thefriction-clutch is suffieient to cause the part, 12, to turn with thedisk, 11, until one of the pins on the part, 12,

engages with one of the lugs, 29, of the regulating-yoke, after whichthe disk, 11, rotates without aecting the disk, 12. When the disk, 11,is reversed, the disk 12 turns back therewith until the opposite pin,26, engages with the opposite part of the yoke, 29. Said yoke, asexplained, is adjustable by means of the hand-wheel, 30, on the front ofthe machine, and When the same is moved it opcrates to further limit orincrease the stroke or oscillation of the disk, 12, and shaft, 18, andconsequenty of the part C. In this manner I make it possible to actuallystop the oscillation of the ratchetepaivls or cause the same to take themaximum stroke of the part, C, imparted thereto through the medium ofthe constantly-driven disk, 1 1. The two pavvls of the ratchet-mechanismWork oppositely that is, one operates to positively move the ratchet,while the other is moving through its return stroke, and it is obviousthat as long as corresponding ends of the double pawls remain inengagement with the ratchc -Wheel, said wheel will be intermittentlyrotated in a single direction. Said rotation of the ratchet-wheel iscontinued until the feed-table of the carving machine has accomplishedthe needful transverse movement upon the bed, whereupon it is stopped toreceive new pieces of work. After the new work has been placed upon themachine, the table need not be manually returned to its originalposition, but may be caused to feed back slowly, by the mere throwing orreversal of the weights, 45, belonging to the double paavls, such changeof position operating to engage the opposite ends of the pavls with theratchet-Wheel and cause it to rotate in the other direction. The motionof the ratchet-Wheel by either of the pawls does not take place untilthe driver is actually reversed. In addition to the foregoing, it shouldbe understood that the table does not immediately take on the motion ofthe driver, because of the cushionsprings that are interposed betweenthe rack, 8, and the bed, and that for this reason the feed-mechanismactually accomplishes its full function of transversely feeding thetable or the chucks thereon, prior to the beginning of the movement ofthe bed and table, in either direction.

rIhe term longitudinal motion or reciprocation as applied to theoperation of the machine, is intended to mean or designate the normal orconstant action of the table; and the terms transverse feed of thetable, transversely feeding the table and the like, are intended to meanor designate the transverse or lateral motion that is imparted either bythe table itself or to any part by Which the feeding of the work in ahorizontal plane or by rotation, is accomplished.

The shafts, 10, 17 and 50 are all connected at the same time, so thatthe work can be turned at will. For instance: If an oval piece of Workwere put on the centers and this piece of Work exceeded in depth thelift of the tracer-bar, it would not swing under the tracer-point if thetracer-point were placed at the center of the pattern with the workrunning directly on the center. IIowever, if the tracer-point is put onthe center of the pattern and both feeds are thrown in, the patternrevolves on the centers and also moves laterally, thus enabling thetracer to reach every part of the pattern and still he Within thelifting range of the retracting mechanism; and when one side of the ovalis finished thereby, the pattern may be turned over and the other sidefinished.

It is obvious that numerous modifications of my invention Will readilysuggest themselves to one skilled in the art, and my invention is notconfined to the specific constructions herein shown and described.

Having thus described my invention, l claim as new and desire to secureby Letters Patent 1.
